Workflow backendfrontend in team development?

Question

Yii

Colleagues, share your experience of team development. How to optimize between frontend and backend?
We now have this:
Frontend:
1. The layout designer uses gulp (jade, sass, webpack, etc).
2. Sources are uploaded to git, dist is collected via CI (dist is then connected as assets on the backend)
Backend
1. The backend manager merges the results of the frontend work, generates dist
2. Cuts the finished html into views, writes logic, etc.
Projects are designed for long-term support rather than done and forgot.
Then, for example, it is necessary to make some improvements to the functionality, make changes, etc.
The process looks like this:
1. The layout designer makes changes, fills in turnips.
2. CI generates a new dist
3. Backendschik takes the code, and he accordingly needs to make changes to the templates, for which you need to compare with the previous dist
It is p3 that I want to optimize to a greater extent. How can you make sure that the front-end back-end does not do double work? Roughly speaking, I want common templates, while not allowing the layout designer to dive deep into the backend logic.
Thank you.
